179 are cords secured to the inner ends of the upper strap members 162and secured at their other ends to the casings 2. The arrangement otsupplemental arms on the inner ends of the armsl is devised to ohviatethe accidental trapping of a horse and vehicle or person upon the trackswhen a train is approaching, that is to say, in the event ot' a trainapproaching and the arms are automatically lowered While the person isdriving over the crossing, a means of egress is provided. ln theoperation ot this portion or the de'- vicethe horse or person presseslagainst the bars 173. 'These hars are very 'light and swing quitereelynpon their pivotsl otilering very little resistance. The swingingof either of the bars 173 withdraws the pins 175 from engagement withthe Weighted arm 171 and saidarm turns the rod 16S and through the'cain169 withdraws the vlatch 166, thereby loosening ,the 'supplemental arxnand said supplemental arm immediately rswings upon its' pivot beingactuated hy the` spring 164, thereby` making 'an opening.

otal on which the pulley is mounted and winds up the cords Sti or 87 asthe case may be` thereby pulling on the respective lever 83 or S1 torelease the corresponding latehl holding up the pivotal weighted member|76 or 77. On the release/.of either of they weighted members or .77 thesaid member t Swings downwardly on its pivot drawing downwardly on thecord attached thereto and operating the signal in the manner described.The cord on being pulled downthrows out the corresponding signal arm,thereby indicating the direction from which the train is approaching.Simultaneously with the movement of the signals, the switch 88 is throwndownwardly by the pin S9 on either of the pivotal weighted membersengaging the] same and said switch closes an electric circuit to thelamps 01 and bell 92 and also closes the circuit to the motor 29 withinthe casing 1l. The clutch lever 41 is normally held by the weight 133 soas to operate the Sprocket chain Q0 and shaft 5 to swing the arms 1downwardly, thereby preventing the crossing of the tracks inadvance ofthe approaching train. W'hen the first pair of wheels of the trainenters the bloclt v0S an eleetric'circnit is closed through the wires 99and 100 througlrthe magnet 101. The magnet 101 being energized draws`the lever armature 101 downwardly allowing the weighted end of thepivotal member 103 tifs .fing downwardly. This move- The weighted memberromaine in this position until the last pair of wheels of the trainleave the block 98. The electric eircuit through the.electro-magnet 101is then broken and the armature 101 being released is thrown upwardly byits operating spring and throws the weighted end otl the member 103upwardly, allowing the pivotal arm 10T to swing downwardly intoelectrical contact with the contact 10S). .\n electric circuiti is thusclosed through the electro magnet 105 and the arn'niture. 10G is attracted thereby, thus holding the said piv member 192') with, itsarmature end down vard. ("oineidently with the operation ol' the member103 the current: flows through the. electro-magnet 118 throwing thelatch 115' clear ot' the grooved pulley lll. The weight suspended t'rointhe pulley lll rotates the .shaft lll. The rotation of t'he shalt 111winds the cord 1% upon the drum 12T. thereby pullin; r the latch 126 torelease the. lever 12?). The weighted lever ti then swings downwardlyrotating the putte)` .t2-" and pulling upon the cord 129 swings theclutch lever l1 upon its pivot, releasing the driving connection betweenthtI halt ill and the sproeke Slt. The

arrestingxot the armsl 1 on reaching their downward position is notdependent on the operation of the lever -ll but the said arms swingingdownwardly draw upon the cord .)T (Fig. 3) 'so as to open the switch lll`:t the limit of their downward moven'ient, th t. breaking the electriccircuit to the motor 29 and arresting its movement. As the lever -tl isswung upon its pivot, the clutch member 30 is moved into engagement withthe clutch 21S and eoiiwidently the switch 12h is opened and the switch1.30 allowed to close in the manner hereinbefort` described.

The opening of the switch 121 breaks the electric circuit to the magnet110 and as the armature 100-is thus released, the lever 193 is turned onits` pivot but the weighted end thereof and the opposite. end coming incontact with the'pivotal member 107 breaks, the circuit at the contact109. The closing of the switch 150 completes the electric circuitthrough the -wires 150 and 160 to the motor Q0, thereby starting thesaid motor into operation. As the clutch on the shaft 31 is now reversedthe cable 153 is Wound upon the drum 3T and through the drum 9 andconnecting gear swings the gates upwardly. Coincidently' with the upwardmovement of the gates the sprocket 135 is rotated thus turning the shaft134. The rod 130 is moved upwardly through the rack 'and pinion 138 andI3? to return the signals to normal and coincidentl-'y the cord 143 iswound upon the drum 142; thereby rais ing the lever 123.
